Cattle guard construction and method

For use in a highway cattle guard, an individual, precast concrete slab section comprising a side-by-side series of individually formed, trough-like lengths of structural sheet material each of which is formed to provide an elongate valley member;

• elongate structural sheet material interconnecting the trough-like lengths as ridges between the valleys thereof and providing up-facing traction surfaces for vehicles crossing the cattle guard transversely of the valleys and ridges;
• a structural concrete base for each of said sections precast integrally into the reverse valleys formed along the underside of the interconnected lengths and extending thickly below the valleys as a supporting slab base therefor integral with the remainder of said concrete base;
• and means securing the interconnecting sheet material in place.

A highway cattle guard, comprising precast, individual, concrete slab sections aligned in end-to-end relationship across a highway as an extension of cattle-confining fencing, each of said sections comprising a side-by-side series of separate lengths of structural sheet material, each of which lengths is formed to provide a valley and to interconnect with sidewise adjoining lengths to provide sidewise adjoining valleys and reverse valleys at opposite faces of the section with ridges therebetween;

• means securing said lengths together in their adjoined relationship;
• concrete cast into place onto and against a face of the sections and into corresponding valleys of the individual lengths of the said series covering corresponding ridges and providing a structural concrete base that is wholly integral and that includes a supporting slab base in common with all of the lengths of said series, the other ridges providing up-facing traction surface for vehicles crossing the cattle guard transversely of the valleys and ridges.
